Craft Cakes?

When I was uploading my newest cake, I once again noticed the button at the bottom that says "This is cake/food and not a diaper cake or craft cake". Now, I understand what a diaper cake is but a craft cake? Is that like the cake dummies?

I only ask because I just received some cake dummies in the mail and once I start practicing with them I would like to upload them for comments/suggestions, if that's allowed.
